Where to find the best popcorn shops in Chicago

The first commercial popcorn machine was invented here in
Chicago and introduced at the Columbian Exposition in 1893. So it's
little surprise that popcorn shops have been popping up in our city
ever since. Here are five that are worth a stop-especially on
National Popcorn Day (Jan. 19.)

Note: You can never go wrong with the Chicago Mix, a classic
invented right in our fair city, but if you're looking to branch
out a little, we have a few new suggestions.
